Is there any Pokemon in Gen 1 that can't be found in any other Generation?

When I say this I don’t mean when Gained Via Poke transfer I mean finding them is water, tall grass, hidden places etc.

When I just say a Pokemon’s name, I also mean it’s evolutionary line (mostly via evolution) unless I put a * next to it.

Therefore, all Gen I Pokemon are available legally in all games.Mew is only available via Pokemon Ranch, and if you can trade,Mew is available. But still, basically all Gen I Pokemon are available in all games. This also excludes the Kanto part of Gold and Silver, and their respective remakes.

Hope I helped. :)Source: Experience,thisand some Pokemon’s Bulbapedia pages.

Umm … Mew? That’s the best I can think of.

Thanks to a glitch in R/B Mew could be encountered like a regular Pokemon (without gamesharks, etc.), but ever since it has only been available via event.

That probably isn’t what you mean, though, so I don’t think there is.

However, I don’t have a source. But quite apart from anything else, all of the Kanto Pokemon were available in GSC, except for the starters, the legendary birds, Omanyte and Kabuto families, Mewtwo (all of which appear in X and Y), and Mew (which has been released in various events.
